In this study, 116 patients, at least 1 month of age but younger than 5 years, were identified with culture-proven bacterial meningitis. A comparison was made between the clinical data of the patients with and without seizures during hospitalization. Seizures during acute bacterial meningitis accounted for 47% (55/116) of the episodes. Time interval between the onset of bacterial meningitis and that of seizures was 1 to 20 days (mean, 4 days). Twelve of these 55 patients had one or more afebrile seizures after completing the treatment. At follow-up of at least 1 year after completing treatment, 26 patients had good outcomes, whereas the other 29 patients had poor outcomes. A strong correlation between the findings of abnormalities through neuroimaging and the occurrence of seizures during hospitalization was observed. The long-term outcomes of patients with infantile and childhood bacterial meningitis, who had seizures during the acute phase of bacterial meningitis, were worse than the outcomes of those who did not have such seizures. No child developed late seizures unless there were acute seizures. Factors associated with seizures during acute bacterial meningitis include disturbed consciousness on admission, abnormal neuroimaging findings, and low glucose and high concentration of total proteins in cerebrospinal fluid.

To determine the epidemiologic trends, prognostic factors, and therapeutic results of neonatal bacterial meningitis, 60 neonatal patients with culture-proven neonatal bacterial meningitis were enrolled in this study. To compare changes over time, the appearance of disease among the patients was divided into two equal periods (1986-1993 and 1994-2001). Group B streptococci were the most common causative pathogens, accounting for approximately 32% of the episodes. Escherichia coli, the next most common pathogen, was more frequently observed in the second period. Seventy-seven percent of gram-negative bacilli isolates were resistant to ampicillin. Moreover, oxacillin-resistant Staphylococcus and ampicillin-resistant group B streptococci strains occurred in the second periods as late-onset neonatal bacterial meningitis. The overall mortality rates for the first and second study period were 17% and 8%, respectively. However, if individuals with poor outcomes were taken into account, 38% of patients were considered treatment failures. Significant prognostic factors included the presence of seizures, thrombocytopenia, and high cerebrospinal fluid protein and low cerebrospinal fluid glucose concentration. Although the mortality rate was significantly reduced in the second period, there has been increasing incidence of the emergence of resistant strains presenting a therapeutic challenge. The presentation in neonatal bacterial meningitis might be nonspecific, and blood culture results were negative in 45% of the episodes. Early diagnosis, choice of appropriate antibiotics, and correction of metabolic derangement are essential to improving outcomes.

The lack of specific symptoms and signs in patients with tuberculous meningitis makes early diagnosis difficult. To our knowledge, there has been no report in the literature focusing on tuberculous meningitis patients younger than 1 year of age. In this report, we reviewed the clinical features and laboratory findings of seven infants with tuberculous meningitis encountered during a 15-year period. All patients had fever, cough, and alternation of consciousness at presentation. Five patients had bulging anterior fontanel, and five had generalized tonic-clonic seizures. The purified protein derivative skin test was positive in six patients. Six patients had hyponatremia. All seven patients had abnormal cerebrospinal fluid findings, and six of them demonstrated cell counts less than 500 cells/mm3 with lymphocytic predominance. Brain sonography examination revealed hydrocephalus in all seven patients. Therefore we conclude that antituberculosis therapy should be promptly initiated in any young infant with a clinical impression of meningitis in the context of cerebrospinal fluid white cell count of less than 500 cells/mm3 and lymphocytic predominance, hyponatremia, and hydrocephalus.
